Historically Useful: Warm Climate Features
Wide, overhanging eaves form a two-story, wrap-around porch to shield the building from the sun, and provide
shaded outdoor work and living space.
Large trees growing near the house provide shade during hot summer months, preventing exterior walls from being
exposed to high temperatures.
Sheltered interior courtyard space like this provides much need shade during hot summer months when high
temperatures make outdoor activities uncomfortable.
Thick adobe walls provide substantial thermal mass that slows passive heating and cooling. Rooms stay cool even
on hot summer days and warm when heated in the cooler months.
Interior shutters like these are not only decorative, but can be closed to keep a room cool by reducing solar gain on
hot days.

14. RECOVERY ACT & NHPA SECTION 106 REVIEWS
The American Recovery and Reinvestment Act of 2009 (Recovery Act) was signed into law by President
Obama on February 17, 2009. Many of the projects funded through the Recovery Act have the potential to
support the preservation and productive use of historic properties.
Recovery Act Projects, like all federal and federally-sponsored programs and projects, are reviewed pursuant
to Sections 106 and 110 of the National Historic Preservation Act. Section 106 of the National Historic
Preservation Act (NHPA) requires federal agencies to consider the effects of proposed federal undertakings
on historic properties. NHPA's implementing regulations found in 36 CFR Part 800, require federal agencies
(and their designees, permittees, licensees, or grantees) to initiate consultation with the State Historic
Preservation Officer (SHPO) as part of the Section 106 review process. SHPO consultations should be
initiated early in the project planning process, BEFORE the project is begun.
What is an undertaking?
Undertaking means a project, activity or program, funded in whole or in part under the direct or indirect
jurisdiction of a federal agency, including those carried out by or on behalf of a federal agency; those carried
out with federal financial assistance; and those requiring a federal; permit, license, or approval. (�800.16
(y))
If the undertaking is a type of activity that does not have the potential to cause effects on historic properties,
assuming such historic properties were present, the agency official has no further obligations under Section
106. (�800.3(a)(1)).
Note: Certain types of projects funded by the Department of Energy (DOE) under the Energy Efficiency and
Conservation Block Grant program (EECBG), State Energy Program (SEP) and Weatherization Assistance
Program (WAP) are categorically exempted from the Section 106 SHPO consultation because they have
been determined to have limited potential to adversely affect historic properties. These projects include
undertakings for planning, training and educational purposes, undertakings to replace equipment on existing
buildings or structures that result in no building or structure changes or ground disturbances, and
undertakings on buildings or structures less than 45 years of age that will result in no ground disturbances.
A list of projects categorically excluded from SHPO review in California is available here.
A copy of the ARRA Programmatic Agreement between the California Energy Commission (CEC),
Department of Community Services and Development, USDOE, and OHP can be viewed here.
What is a historic property?
A historic property is any prehistoric or historic district, site, building, structure, or object included in, or
eligible for inclusion in, the National Register of Historic Places. For more information see National Register
Bulletin 15, "How to Apply the National Register Criteria for Evaluation."

Re: Energy Upgrade California Preservation Working Group Recommendations and
Suggestions for Improving Upgrade Performance on Older Homes and Reduced
Approval Times.
Congratulations on choosing to own an older home,
An increasing body of work continues to confirm that buildings constructed prior to
widespread air conditioning or even central heat, perform better than most homes
constructed prior to the mid-1980’s. They also were typically constructed of more durable
materials than modern buildings which improve sustainability as well.
We are providing materials for your review which we hope will help you make upgrade
decisions that will preserve both historic materials and passive comfort features often built
into our older homes. You should be aware that all structures forty five years old and
older will need to be evaluated per the federal Historic Preservation Act of 1966 in a
process called Section 106 review. As is commonly done on large programs like this, the
State Historic Preservation Officer (SHPO) has signed a Programmatic Agreement (PA)
with the relevant federal funding agencies to provide an expedited review process. For
the vast majority of projects that do not involve window replacement or solar panel
installation, this will reduce your historical review process to a few weeks versus five
months to a year or more. The Section 106 process if the main evaluation, but if your
home is also on the National Register of Historic Places, is a local landmark or is in a local
historic district, you should also expect to have a review by your community historic
review body. While this should be mostly a formality for PA or Section 106 approved work,
they may have additional requirements that you should make yourself aware of prior to
selecting upgrade measures. Your preservation board can typically be contacted
through the local Planning or Community Development Department.
We will begin with an overview of the materials in the package provided and some
additional comments and/or corrections as they apply to the climate and regulations of
our area. The second portion will be a checklist of the minimum materials needed for
your historical review submittal and a request for supplemental materials to improve the
quality of the findings as well as reduce the processing time.
